Continuing increases in leisure time, income, greater mobility, levels of education, and general health have whetted and nourished the American appetite for outdoor recreation activities. Statistics indicate that almost every American engages in one or more recreation activities when he or she is at all able. Measured by the number of recreation occasions, American outdoor recreation activity increased by 53 percent between 1960 and 1965. From 1965 to 1980, it will increase by another 59 percent. With more and more Americans continuing to turn to outdoor recreation activity, pressures on public and private recreation resources and facilities far exceed previous expectations.
